Set up a proportion
5 blown away/7 total= 30 blown away/ x total
5*6=30
7*6=42 total
42 total-30 blown away= 12 left
Final answer: 12
One way is to subsitute the point (-1,5) for every function and see which one gives a true statement
5=10(2)^(-1) is true
5=10(0.5)^-1 is false
5=5(-1) is false
5=5(2)^-1 is false
answer is y=10(2)ˣ
Answer:
(2,4) is not a solution
Step-by-step explanation:
(2 , 4)
2 + 2*4 = 10 > -2
X = -7. Hope this helps...
